Number (1–3,999 for numerals)

Roman numeral

1,154 is written MCLIV in Roman numerals. That is 4 symbol groups added together, reading left to right from the largest value down.

How it breaks down

MCLIV = 1000 + 100 + 50 + 4 = 1,154
Group	Value	Subtraction	Running total
M	1,000	—	1,000
C	100	—	1,100
L	50	—	1,150
IV	4	V − I	1,154

Why the smaller symbol comes first

MCLIV uses subtractive notation in one place: IV means V minus I, or 4. A smaller symbol placed before a larger one is subtracted from it rather than added, which is why IX is nine and not eleven.

Only six such pairs are valid — IV, IX, XL, XC, CD and CM. That restriction is what makes the notation unambiguous: IIII and IC both look like they should work, but neither is standard, and only one spelling of any number is correct.
